Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42958, here are decompositions:

  • 5 + 42953 = 42958
  • 29 + 42929 = 42958
  • 59 + 42899 = 42958
  • 137 + 42821 = 42958
  • 191 + 42767 = 42958
  • 239 + 42719 = 42958
  • 257 + 42701 = 42958
  • 269 + 42689 = 42958

Showing the first eight; more decompositions exist.
